Abstract
The dependence of the nitrogen reduction rate on N2-concentration under high nitrogen pressures was measured. The reason for the sharp break of the Arrenius curves in nitrogenase reactions at 20 degrees C was examined. The influence of nitrogen on isotope effect catalyzed by nitrogenase was studied. The kinetic schemes that explain the peculiarities of the nitrogenase reactions were analyzed by the graph's theory. On the base of new conception of inhibitor-"interceptor" of electrons the literature data were discussed.
摘要
测定了在高氮压力下氮还原速率对N2浓度的依赖性。研究了在20℃时固氮酶反应中阿累尼乌斯曲线急剧转折的原因。研究了氮对固氮酶催化的同位素效应的影响。用图论分析了解释固氮酶反应特性的动力学方案。基于抑制剂——电子“拦截器”的新概念对文献数据进行了讨论。
